How do I mask an image in unity?

2. Masks

1. To create the Mask, First create a new UI image. You can do this by selecting GameObject > UI > Image from the top toolbar.
2. Next, add a Mask component to the UI Image you just created. This can be done by selecting Add Component in the Inspector and choosing UI > Mask.
3. Parent a Raw Image to this mask.

How do masks work in unity?

A Mask is not a visible UI control but rather a way to modify the appearance of a control’s child elements. The mask restricts (ie, “masks”) the child elements to the shape of the parent. So, if the child is larger than the parent then only the part of the child that fits within the parent will be visible.

What happens when you move a mask in Unity?

The areas of the child Image outside the panel will become invisible since they are masked by the shape of the Panel. If the image is then moved around then only the part revealed by the Panel will be visible. The movement could be controlled by Scrollbars to create a scrollable viewer for a map, say.

How to make an image invisible in Unity?

You can achieve this by firstly making the Image a child of the Panel object. You should position the Image so that the area that should be visible is directly behind the Panel area. Then, add a Mask component to the Panel. The areas of the child Image outside the panel will become invisible since they are masked by the shape of the Panel.

Is there a lit shader mask map in Unity?

No, and there won’t be unless Unity decides to allocate time. Instead you will pack them using substance, or art package or utility as above OR just use shader graph to route the channels of interest. I recall Unity talking about various options for this but I don’t think anything concrete came of it.

How is masking implemented in the GPU in Unity?

Masking is implemented using the stencil buffer A memory store that holds an 8-bit per-pixel value. In Unity, you can use a stencil buffer to flag pixels, and then only render to pixels that pass the stencil operation. More info See in Glossary of the GPU.
